Lock Nuts

1,701 products

Locknuts lock fasteners in place to keep them from backing out or loosening due to vibration or torque. A locknut is commonly used in place of a standard nut on vibrating machinery and when joining soft materials. Types of locknuts include those with serrated flanges or tooth washers that dig into surfaces and those with nylon inserts or deformed threads that grip tightly onto fastener threads. Reversible locknuts (also called center locknuts) can be started from either side for flexibility with installation.
